Descrição

The PX293 Series has been DISCONTINUED. Please refer to the PX157 Series as a possible substitute.

The PX293 Series of differential pressure transducers are designed to measure differential pressures of liquids or gases. A broad range selection is available to meet most industrial and laboratory applications. The transmitters are housed in a rugged, gasketed, cast aluminum case that’s designed to NEMA 4 and IP65 standards. Wall mounting holes are enclosed in the casting. Access to the terminals is made through 1 /2 " conduit knockouts on the front of the box. There are no moving parts and the transducers are virtually position insensitive. The span and zero adjustments are made via 20 turn potentiometers for easy, fine adjustments. The pressure transmitter uses two high accuracy, high stability piezoresistive sensors with stainless steel isolation diaphragms. Either sensor may be disconnected without overpressurizing the other.
